[0031] Please refer to Figures 1-2 The utility model discloses a steam boiler, including boiler main body 2, temperature control circuit, power interface 20 and first heating assembly 3 and second heating assembly 4. Wherein, boiler main body 2 is used to hold water, power interface 20 sets up on boiler main body 2, first heating assembly 3 and second heating assembly 4 set up in the inside of boiler main body 2 for heating water, first heating assembly 3 and second heating assembly 4 pass through temperature control circuit and power interface 20 electric connection.

[0032] In the working process, the temperature control circuit controls the working states of the first heating assembly 3 and the second heating assembly 4 according to the temperature. When the temperature inside the boiler body 2 is in the preset first temperature range, the temperature control circuit connects the first heating assembly 3 and the second heating assembly 4 to the power interface 20 at the same time, so that the first heating assembly 3 and the second heating assembly 4 obtain power from the power interface 20 at the same time, thereby heating the inside of the boiler body 2 at the same time, rapidly increasing the water temperature in the steam boiler in the double-component heating mode, and making the water temperature reach the preset heating temperature, thereby greatly shortening the waiting time of the user and improving the heating efficiency. When the temperature inside the boiler body 2 is in the preset second temperature range, the temperature control circuit only connects the first heating assembly 3 to the power interface 20, and controls the second heating assembly 5 to be disconnected from the power interface 20 at the same time, so that only the first heating assembly 3 obtains power from the power interface 21 to heat the inside of the boiler body 2. At this time, the steam boiler works in the single-heating-component mode, maintains the stable output of steam, reduces power consumption, avoids frequent action of the temperature control circuit, and improves energy efficiency.

[0033] As shown in Figure 2 and Figure 4 , the temperature control circuit includes a first temperature controller 24 and a second temperature controller 25, the first heating assembly 3 is connected to the power interface 20 through the first temperature controller 24, and the second heating assembly 4 is connected to the power interface 20 through the second temperature controller 25. The first heating assembly 3 and the second heating assembly 4 are arranged in parallel in the boiler body to optimize the heating uniformity and space utilization, and improve the heating efficiency and overall structural stability. Specifically, the first temperature controller 24 and the second temperature controller 25 are both recoverable temperature controllers, which are normally closed, and can sense the temperature change inside the boiler body 2 in real time, and control the first heating assembly 3 and the second heating assembly 4 to be connected or disconnected from the power interface 20 according to the temperature change.

[0034] Further, as shown in Figures 2-3 , a temperature sensing area 26 is further arranged in the boiler body, which is the highest temperature area of the boiler body during heating, and the highest temperature area of the boiler during heating. The first temperature controller 24 and the second temperature controller 25 are both arranged in the temperature sensing area 26, so that the first temperature controller 24 and the second temperature controller 25 can more accurately sense the actual working temperature in the steam boiler, and switch the on-off state when the preset temperature threshold is reached.

[0035] In this embodiment, the first temperature controller 24 is set to disconnect the first heating assembly 3 from the power interface 20 when the temperature of the temperature sensing area 26 is in the third preset temperature range, and to connect the first heating assembly 3 to the power interface 20 when the temperature of the temperature sensing area 26 is in the first temperature range; the second temperature controller 25 is set to disconnect the second heating assembly 4 from the power interface 20 when the temperature of the temperature sensing area 26 is in the second temperature range, and to connect the second heating assembly 4 to the power interface 20 when the temperature of the temperature sensing area 26 is in the first temperature range.

[0036] In this embodiment, the lower limit temperature of the third temperature range is greater than the upper limit temperature of the second temperature range, and the lower limit temperature of the second temperature range is greater than the upper limit temperature of the first temperature range. After the steam boiler is powered on, the first temperature controller 24 and the second temperature controller 25 simultaneously connect the first heating assembly 3 and the second heating assembly 4 to the power interface 20, so that the first heating assembly 3 and the second heating assembly 4 are simultaneously heated. Due to the large power, the water can be quickly heated to a boiling state, and steam is quickly generated and output, greatly shortening the user waiting time. When the temperature of the temperature sensing area 26 gradually rises to the second preset temperature range, the second temperature controller 25 disconnects the second heating assembly 4 from the power interface 20, so that the second heating assembly 4 stops working, and only the first heating assembly 3 continues to operate. In this stage, the steam boiler works in a single heating body mode, the power is reduced, but the stable output of steam can still be maintained, avoiding the problem of frequent on-off of the temperature control circuit due to excessive power, and effectively prolonging the service life of the boiler. If the steam usage decreases or the temperature of the temperature sensing area 26 continues to rise to the third preset temperature range, the first temperature controller 24 disconnects the first heating assembly from the power interface 20, so that the first heating assembly 3 also stops working, and the steam boiler enters a standby protection state. As the temperature of the steam boiler decreases, when the temperature respectively falls to the second preset temperature and the first preset temperature, the first temperature controller 24 and the second temperature controller 25 respectively connect the first heating assembly 3 and the second heating assembly 4 to the power interface 20, and the boiler starts heating again to quickly restore steam output.

[0037] In an embodiment, the boiler body 2 is provided with a steam outlet 23, and an outer shell 1 is arranged outside the boiler body 2 to protect the boiler body 2. The outer shell 1 can be made of high-temperature-resistant and corrosion-resistant materials, and is tightly matched with the boiler body 2 to ensure the sealing property. A water inlet is formed on the boiler body 2 and communicates with a pressure relief valve 5 on the outer shell 1. The pressure relief valve 5 is arranged at the top of the outer shell 1 or at a position convenient for operation, and the user can add water to the boiler through the pressure relief valve 5. When the internal pressure of the boiler is too high, the pressure relief valve 5 will automatically open to release the excess pressure, avoiding damage to the equipment or dangerous situations caused by abnormally high internal pressure.

[0038] Specifically, the boiler body 2 comprises an upper boiler body 21 and a lower boiler body 22 connected with each other. The lower end opening of the upper boiler body 21 and the upper end opening of the lower boiler body 22 are connected by a sealing structure, for example, a high-temperature-resistant sealing gasket or other sealing element, to ensure the sealing of the inside of the boiler body 2. The first heating assembly 3 and the second heating assembly 4 are both arranged on the lower boiler body 22, wherein the power of the first heating assembly 3 is greater than that of the second heating assembly 4, and the second heating assembly 4 serves as an auxiliary heating function. In addition, the pressure relief valve 5 and the water inlet are arranged on the upper boiler body 21, and users can conveniently inject water through the water inlet and safely discharge pressure through the pressure relief valve 5, further improving the convenience and safety of the equipment.

[0039] In the embodiment, the first heating assembly 3 and the second heating assembly 4 can be arranged as circular heating pipes or other shapes of heating body structures, which are not limited herein.

[0040] The utility model embodiment further provides a steam mop, which comprises a steam pipeline 6, a steam handle 7 and the steam boiler described above, and the steam pipeline 6 is connected between the steam boiler and the steam handle 7. A button 8 is arranged on the steam handle 7, and the button 8 is used for controlling the opening and closing of steam. When a user operates the button 8, steam in the steam boiler can be transmitted to the steam handle 7 through the steam joint 23 and the steam pipeline 6 and output, realizing flexible control of steam output.

[0041] Further, the steam mop further comprises a control valve, which is installed at a position close to the steam joint 23 of the steam pipeline 6 and tightly matches with the inner wall of the steam pipeline 6, and is used for adjusting the flow of steam. In actual use, a user can adjust the opening of the control valve according to cleaning requirements, for example, when cleaning light stains, the control valve is adjusted to a small opening, low-flow steam is output, and energy is saved; when dealing with stubborn stains, the control valve is adjusted to a large opening, high-flow steam is output, and the cleaning process is accelerated. In addition, the control valve can also be designed in linkage with the button 8, when the button 8 closes the steam, the control valve synchronously closes the steam flow path, ensuring that the steam stops outputting.

[0042] It should be noted that each of the embodiments in the present specification is described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same and similar parts between each embodiment can be referred to each other.

[0043] The above describes only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
